Valworx 531510 Pneumatic/Manual stainless ball valves are typically used for on-off control of air, water, oil, and other media compatible with the materials of construction. Unique three piece investment cast bolted body design offers the advantage of a swing out body for easy inline maintenance. Double acting actuator design uses an air pressure signal (80-120 PSI) to open and close the valve. The de-clutch option can be used for manual operation or to set a limit stop for opening or closing. High temperature valve mounting kit available for extended temperature range or wall mounting applications. Advantages of pneumatic/manual ball valves over other type valves may include: higher flow rates, higher pressures, higher temperatures, wider media compatibility, straight through flow path, reduced water hammer, and use in hazardous environments.
Clocked mounting orientation is standard (actuator perpendicular to pipeline). In-line mounting option (actuator parallel to pipeline) available. Select as an option on the Accessories tab.
